To all 2070 0711, it may concern.-

Be it known that we, WILLIAM EDGAR MADmsoN, of High street, and WVALTER DOWNS, of Manton street, Irthlingborough, in the county of Northampton, England, subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Nailing, Slugging, or Like Machines for Use in Boot and Shoe Manufacture, of which the following is a specification.

This invention relates to machines for stubbing or inserting nails, wire pegs, or the like in the soles or heels of boots or shoes, our objects being to simplify the construc tion of the apparatus and generally to increase the efficiency and durability of such machines.

In the accompanying drawings, Figure 1 is a side elevation, and Fig. 2 a front elevation, of a machine embodying our improvements. Figs. 3 and 4: are corresponding views, on a larger scale, of the top portion of the machine, while Figs. 5, 6, 7, 8, 9, and 10 are detail views.

A machine constructed according to our invention preferably comprises a main shaft a, journaled in the frame A, secured to the pedestal B. The shaft a is provided with suitable cams for operating the several working parts. A length of wire 07* is fed to the machine between a toothed. feed-wheel a and a roller a, the toothed wheel a bein intermittently rotated by means of a ratchet- Wheel a secured to the same spindle a as the toothed wheel, and a ratchet-lever a provided with the pawls a a for engaging the ratchet-wheel and having one end drawn down by means of the spring a so that the other end is engaged by the stop a", thereby retaining the pin a in the path of the cam b on the main shaft. The stop a? is secured by means of a set-screw 0, which passes through a slot in the shank of the stop, so as to ad.- mit of the said stop being raised and lowered, and thereby permitting the distance through which the feedwheel rotates to be adjusted. The spindle a on which the feedwheel a/ and ratchet-wheel a are secured, is mounted eccentrically in a hollow spindle b, which by means of a hand-lever b may be turned in the boss I) of the frame A in order to throw the feed-wheel a into or out of contact with the wire (1*. The feed-wheel may be retained in contact with the wire by means of a spring I) 011 the hand-lever b and by providing several holes b in the hand-lever for the reception of the end of the spring the pressure of the feed-wheel on the wire may be adjusted. As the wire (W is fed forward it is received in a hole in a carrier 0, which is reciprocated by means of a cam c, which is adapted to operate a lever 0 pivoted on the pin 0 and connected at one end to the carrier 0 by means of a link 0*. The wire having entered the hole in the carrier, the latter is moved by the cam in such a manner as to shear off and to carry forward a length of wire, so that it arrives in position beneath a plunger d before the latter descends. After the wire has been inserted in the leather and the plunger withdrawn the carrier 0 is returned. to its first position by the pull of the spring 0'' on the lever 0 This spring is secured at one end to the pin 0 on the lever c and at the other end to the collar 0 which is secured adjustably to the standard 0 The plunger 61 is secured to a slide (1, adapted to be raised by a cam (Z on the main shaft engaging the projection d and lowered by a spring d, which surrounds a spindle d in contact with the end of the slide d and guided by the adjustable bridge 61 Leather washers (1 may be employed to deaden the shock when the slide is forced down by the spring. To inclose the carrier 0 within its groove or guideway c, a plate 0, formed with a perforated nozzle or guide 6 is provided, the hole through the latter being in alinement with the plunger (1 The boot or shoe is supported beneath this nozzle. As the plunger d descends it expresses the severed portion of wire from the hole in the carrier 0 through the nozzle 6 and into the leather without permitting the same to become bent. The plunger and carrier are then returned and the several operations are repeated.

A device for feeding the work forward equal distances after each operation may be provided, consisting of a spur f, adapted to be brought down upon the work and then moved laterally. The said spur is attached to a bell-crank lever f, mounted on a pivot f passing through a slot f 3 in a suitable bracket f. In order to maintain the bell-crank lever f in close sliding contact with the bracket f the spring f is arranged to press against the washer f and the head of the pivot f Another slot f is also formed in the bracket f and a pin f which passes through this slot and has vertical play therein, is secured to the bell-crank lever f. A lever g, pivoted at g to the frame A, is adapted to be vibrated by means of a cam g on the main shaft and a spring 9 the latter being secured at one end to the collar (2 and at the other end to the pin 9 on the lever g. The pin 9' is connected, by means of a link g", with the bell-crank lever f Rotary motion is transmitted from the cam g to the said bell-crank lever, thereby depressing the spur f until the pin f8 contacts With the lower edge of the slot f which serves as a stop, whereupon the bell-crank lever, together with the spur, is moved along until the end of the slot f e11- gages with the pivotf The means for supporting the work beneath the nozzle 6 consists of a horn it, which is adjustably secured, bymeans of a set-screw h, to the vertical spindle 72/ mounted in the brackets 71,3 Zr and pressed in an upward direction by a spring h", inserted between the bracket Zr and the collar h. The lower end of the spindle 7L2 is connected by a link 717 to one end of a foot-lever 7L8, pivoted at 72/ to a bracket 2', bolted to the bottom of the pedestal B. The other end of the foot-lever 7Z8 is connected by a rod or link i to a lever i pivoted to the frame A and having at its end a roller i which bears upon a cam j 011 the main shaft a. The cam j is so arranged that after each nail has been inserted in the boot or shoe the horn 7b is lowered in order to allow the spur f to effect the forward movement of the leather. By pressing with the foot on the lever it the horn may be held in its depressed position in order to permit of the work being inserted or removed.

The main shaft a is rotated by means of a friction-clutch consisting of two parts Z5 and 7c. The portion 7c is free to rotate on the V shaft and is formed with a belt-pulley k on one side and an internal bearing-face on the other. A loose pulley 7c is provided. The part Zc of the clutch is secured against rotation on the shaft, but is free to move endwise and is formed with a conical bearingsurfacek for engaging the internal surface on the part 762. A suitable spring is interposed between the two parts of the clutch. A slide Z, having an inclined surface, is adapted to engage the correspondingly-inclined surface of a wedge-piece Z, loosely mounted on the shaft a, and thereby to press the part Zr of the clutch against the part k The slide Z is operated through a rod Z by means of a second foot-lever Z pivoted on the bracket i. Upon the foot-lever being depressed the slide Z is raised, thereby engaging the clutch at the same time the brake-band m, one end of which is attached to the frame A and the other to the arm m of the rod Z is diseneimve gaged from the part 7c of the clutch. The slide Z has secured to it a pin n, having at its outer end a roller W, which when the slide is in its lower position rests upon a depression 0 in a cam-surface formed on the boss 0 of the clutch member k. l/Vhen the slide Z is raised and the part of the clutch starts to rotate, the roller n on the pin it is engaged by the boss 0, and the slide will not be free to descend until the depressed portion 0 reaches a position beneath the roller.

What we claim as our invention, and desire to secure by Letters Patent, is
